The Firestorm Halberd is an Air/Fire Shadowforged Armor released on November 30th, 2016 in the new "Seasons" Shadowforged Event for Season 5. It is effective against Water/Spirit armors, but ineffective against Earth/Water armors. This is also the only Seasonal Shadowforged armor released that does not have Stun as its Special Ability - this armor has First Strike instead.

When first released, the Regular version of this armor had different stats, but they were changed. Originally this armor had base stats of 3367/2986 with 11/10 per level increases (level 99 would be 4445/3966, 48/42 per Ascension level), so the max was 4925/4386. However, now the stats are as they are displayed above.
